Process studies for photocatalytic rejuvenation of spent industrial Bayer liquor. A new low-energy photocatalytic process for the continuous treatment of spent liquor from the Bayer process for alumina production has been demonstrated. This new technology can process up to 1500 litres of industrial caustic effluent per day with a reduction in carbon dioxide release. The photo-treated refinery wastewater also provides water savings of 30 per cent.
Design and Optimisation of Spinning Cone Columns. This project will optimise the design and operation of spinning cone columns, a novel industrial distillation technology that has been developed in Australia. Novel and significant outcomes include applying Computational Fluid Dynamics to the design and optimisation of food processing equipment, understanding fundamental modelling issues in simulating strongly swirling flows, and allowing scale-up to be performed reliably from first principles. ....Design and Optimisation of Spinning Cone Columns.

Novel and significant outcomes include applying Computational Fluid Dynamics to the design and optimisation of food processing equipment, understanding fundamental modelling issues in simulating strongly swirling flows, and allowing scale-up to be performed reliably from first principles. The result will be a "virtual model" of the equipment, allowing design and optimisation of the equipment to be performed from first principles.Read moreRead less
Depressing pyrite in selective flotation of complex polymetallic ores . This project aims to understand the reactions taking place on the major gangue (waste) mineral during the recovery of base-metal and precious minerals. The mining industry is processing low grade complex ores and experiencing difficulties in rejecting gangue minerals in mineral separation and metal extraction plants. The project will develop new technologies that manipulate these reactions to achieve mineral separation and ....Depressing pyrite in selective flotation of complex polymetallic ores . This project aims to understand the reactions taking place on the major gangue (waste) mineral during the recovery of base-metal and precious minerals. The mining industry is processing low grade complex ores and experiencing difficulties in rejecting gangue minerals in mineral separation and metal extraction plants. The project will develop new technologies that manipulate these reactions to achieve mineral separation and metal extraction efficiently and economically. These technologies may provide value in processing low quality complex polymetallic resources using low quality water, whilst halving the operating costs of mineral concentrators and providing corresponding reductions in harmful emissions.Read moreRead less
